摘要
研究考虑了基于苯乙烯-丙烯酸分散液 Lacroten 244 的可聚合复合材料的物理化学特性。研究证实，可聚合凝胶在镁合金上的煤化作用可形成发达的表面结构，对金属和涂料具有良好的粘附性。通过 X 射线光电子能谱和扫描电镜分析研究了这种结构的形成机理及其粘附性能。研究表明，多孔结构是丙烯酸与表面氢氧化镁发生缩聚化学反应的结果。在低碳钢上，苯乙烯-丙烯酸分散体的聚合伴随着强烈的界面相互作用，随后增加了均匀的聚合物涂层。研究表明，苯乙烯-丙烯酸分散体可用于在镁合金和钢材上获得具有高保护性能的经济有效的转化涂层。
Conversion coatings for magnesium and steel alloys based on styrene-acrylic dispersion
Physicochemical properties of polymerizable composite materials based on styrene-acrylic dispersion Lacroten 244 are considered. It is established that polymerizable gels at coaliscence on magnesium alloys form developed surface structures with good adhesion to metal and paints. The mechanism of formation of such structures and their adhesive properties were investigated by X-ray photoelectron spectroscopy and SEM analysis. It has been shown that the porous structures arise as a result of the chemical reaction of polycondensation between acrylic acid and surface magnesium hydroxides. On low-carbon steel, polymerization of the styrene-acrylic dispersion is accompanied by a strong interfacial interaction with subsequent increase in a uniform polymer coating. It is shown that styrene-acrylic dispersions can be used to obtain cost-effective conversion coatings on magnesium and steel alloys with high protective properties.
